1 results about "Tartronic acid" patented technology

The application discloses a kind of bimetallic load Ti-SBA-15 catalyst and its preparation method and application, belong to catalytic preparation technical field.The bimetallic catalyst is CoCu, the loading of CoCu is 5~25wt% of catalyst, the mass ratio of Co and Cu is 0.25~4:1;The catalyst can be successfully prepared by one-step hydrothermal synthesis-isovolume impregnation composite method, and the catalyst is obtained by impregnating and dispersing cobalt precursor and copper precursor on Ti-SBA-15 carrier;The catalyst can be applied to the reaction of selectively oxidizing glycerol to prepare tartronic acid, wherein the oxides of the two metals in the catalyst have a synergistic effect on the oxidation reaction, and the selectivity of the target product tartronic acid is higher than that of single metal, realizing efficient conversion (conversion rate >60%) of glycerol and high selectivity (selectivity >50%) of tartronic acid.
